We have been experiencing an unusually warm winter in London as well. I don't have magnolias but I'm sure the daffs, crocus will sprout sooner than expected as it had last year if the temps (50's) continue to be so. However, they predict a cold set late this month.

My garden has survived cold winters so, Im not worried about that. What is worrying is a very hot summer which they have warned will be hotter than last year and should break records. In anticipation of that and a hose pipe ban, I have bought plastic barrels which are filling up with rainwater. There is nothing I can do for the garden now but I'd like to be able to save it from getting scorched in the summertime.
